Rutgers University- New Brunswick is a public four-year institution located within the limits of New Brunswick and Piscataway, New Jersey. Separated into four sub-campuses, Rutgers University – New Brunswick has developed an intricate campus transit system. Rutgers is one of many institutions who have sought to become more sustainable entities, in order to continue to provide exceptional services to students for the foreseeable future. In order to do so, universities are beginning to look towards alternative methods of transportation for their students to limit the use of private vehicles. This thesis research highlights the weekend accessibility of the four major campus libraries on the New Brunswick campus of Rutgers, comparing the usage of the campus transit system and one’s private vehicle. Using the potential interaction model of accessibility, this research measures the accessibility of each sub-campus to the library on the other 3 sub-campuses and each library to students coming from the other sub-campuses. The results of this research show which campus library is the most accessible to students from the other sub-campuses and which sub-campus is the most accessible to the 3 other libraries. This research also highlights the accessibility gap between students who take the campus transit system and those who make use of their private vehicle.
